Early or excessive sexualized behaviors and preoccupations with sexuality (SB) exhibited by juveniles who have sexually offended (JSO) are considered risk factors for sexual recidivism. However, research into SB among JSO is scarce. The present study retrospectively examined prevalence rates and patterns of SB among JSO prior to sexual offending and their relation to psychopathology and sexual recidivism.

The aim of the current paper was to examine temperament profiles and temperament dimensions as risk factors for persistent criminal behavior in juveniles who offended (JOs). A sample of 137 male adolescents from a Swiss detention center and 137 age and sex matched community controls were included in the present study. Temperament was measured with the Junior Temperament and Character Inventory (JTCI).

Interpersonal trust has been described as a core dimension of cooperative, mutually beneficial interpersonal relationships but it is unclear if it is related to antisocial behaviours in youth. The present study aimed at analysing a subsample of male juveniles who committed serious violent offenses and met criteria of conduct disorder (JO/CD), and a subsample of healthy controls (HC) using a series of trust games (TGs). Twenty-four male JO/CD and 24 age matched male HC performed a series of eight one-shot TGs against different unknown human respectively computer opponents.

The impact of negative life events, self-esteem, and coping behaviour are considered to be contributing factors in the development of emotional and behavioural problems. Differences in the predictive value of these three factors on emotional and behavioural problems from adolescence to adulthood have not yet been studied. Multiple linear regressions separate for the two sexes were used to assess whether the impact of negative life-events, self-esteem, and coping behaviour predicted emotional and behavioural problems at four discrete measurement points from early adolescence to middle adulthood in a cohort of N = 366 participants from a Swiss longitudinal community study.

There is ongoing debate about whether specialized treatment is effective to reduce sexual recidivism in juveniles who have sexually offended (JSOs). Although most treatment programs are based on cognitive behavioral therapy principles for preventing sexual offending, accordant scientific evidence is poor. Following CONSORT guidelines, the present study aimed to evaluate two versions of a short-term outpatient treatment program for JSOs in Switzerland: (a) the Therapy Program for Adequate Sexual Behaviors Version 1 (ThePaS-I), which included offending-specific skills training; (b) the ThePaS-II, which included general socioemotional skills training.

Despite high rates of adverse childhood experiences (ACEs) and personality-related disturbances among delinquent juveniles, associations among ACEs, youth personality, and juvenile crime involvement are still unclear. High-risk samples of institutionalized youth are in specific need of a comprehensive assessment of ACEs and personality features in order to broaden the current knowledge on the occurrence and persistence of juvenile crime and to derive implications for prevention and intervention. We examined a heterogeneous high-risk sample of 342 adolescents (35.

This longitudinal study aimed to evaluate a newly developed cumulative measure for substance use problems as predictor of criminal recidivism in youth. Questionnaires-based substance-related behaviors (tobacco, alcohol, cannabis and further drugs), and interview-based psychiatric disorders were assessed in a sample of 142 male adolescent forensic outpatients in Zurich, Switzerland (mean age 16.8 years, SD = 1.

Research has identified meaningful subtypes among the heterogeneous population of juveniles who sexually offended (JSO). However, studies that test the validity of risk assessment tools with JSO subtypes are limited. This study compared JSO who offended against a child victim (JSO-C) and JSO who offended against an adolescent/adult victim (JSO-A) with regard to rates of recidivism and the predictive validity of two risk assessment tools (Estimate of Risk of Adolescent Sexual Offense Recidivism [ERASOR] and Juvenile Sexual Offender Assessment Protocol-II [J-SOAP-II]).

Understanding the dysregulation profile (DP) consisting of high scores in aggression, attention problems, and anxious/depressed problems is still limited. The aims of the present study were threefold: (a) to analyze developmental trajectories of DP (b) to identify predictors of these trajectories, and (c) to study the outcome of DP in terms of mental disorders and criminal offenses in young adulthood. A sample of 402 individuals aged 11-14 years at baseline was followed up during adolescence and young adulthood.

The present examination raises the question whether attrition in a longitudinal study leads to biased findings. The Zurich Adolescent Psychology and Psychopathology Study (ZAPPS) originated in 1994 by following a sample of 1239 adolescents with follow-ups after three, six, and 22 years. The study collected data on life-events, self-esteem, and coping behavior as independent and mental problems as dependent variables.

Conduct disorder (CD) is a heterogeneous pattern of rule-breaking and aggressive symptoms. Until now it has been unclear whether valid, clinically useful symptom profiles can be defined for populations in youth at high-risk of CD. Interview-based psychiatric disorders, CD symptoms and officially recorded offences were assessed in boys from a detention facility and a forensic psychiatric hospital (N = 281; age 11.

Although accurate risk appraisals are mandatory to provide effective treatment to juveniles who have sexually offended (JSOs), the current knowledge on the validity of risk assessment instruments for JSOs is inconclusive. We compared the predictive validities of the Juvenile Sex Offender Assessment Protocol II (J-SOAP II), the Estimate of Risk of Adolescent Sexual Offense Recidivism (ERASOR), and the Violence Risk Appraisal Guide-Revised (VRAG-R) scores concerning sexual, nonsexual-violent, and general criminal recidivism (based on both official and nonregistered reoffenses) in a consecutive sample of 597 male JSOs (Mage = 14.47 years, SDage = 1.

The development of sexuality is a major goal in the normative course of puberty. However, some adolescents start and maintain sexually coercive behaviors. Maltreatment appears as a contributing factor in juvenile criminal persistence, although its role regarding reoffenses in juveniles convicted of sexual offenses (JSOs) is unclear.

Background: Discrepancies between multiple informants often create considerable uncertainties in delivering services to youth. The present study assessed the ability of the parent and youth scales of the Strength and Difficulties Questionnaire (SDQ) to predict mental health problems/disorders across several mental health domains as validated against two contrasting indices of validity for psychopathology derived from the Development and Well Being Assessment (DAWBA): (1) an empirically derived computer algorithm and (2) expert based ICD-10 diagnoses.

Methods: Ordinal and logistic regressions were used to predict any problems/disorders, emotional problems/disorders and behavioural problems/disorders in a community sample (n = 252) and in a clinic sample (n = 95).

Background: Adverse childhood experiences (ACEs) and psychiatric disorders are common in juvenile detainees. Emotional dysregulation resulting from cumulated ACEs may be characterized by symptoms of irritability. The present study examined whether the accumulation of ACEs, irritability, or both predicted mental disorders in incarcerated adolescents with and without controlling for one another and for socio-demographic factors.

Youth- and parent-rated screening measures derived from the Strengths and Difficulties Questionnaire (SDQ) and Development and Well-Being Assessment (DAWBA) were compared on their psychometric properties as predictors of caseness in adolescence (mean age 14). Successful screening was judged firstly against the likelihood of having an ICD-10 psychiatric diagnosis and secondly by the ability to discriminate between community (N = 252) and clinical (N = 86) samples (sample status). Both, SDQ and DAWBA measures adequately predicted the presence of an ICD-10 disorder as well as sample status.
